4.5 V AA battery holder
This holder fits three 1.5 V AA cells to deliver a 4.5 V supply for low-power projects. The ABS case weighs 28 g and measures 160 mm in length, making it a compact external power source. An integrated on-off switch lets you control power without disconnecting wires. Batteries are not included.
Sustained-load behaviour
The ABS enclosure provides basic insulation but no active cooling, so continuous current is limited by the cells' own chemistry and internal resistance. Voltage will sag gradually as the batteries discharge, and the holder itself adds minimal series resistance. It is suited for intermittent or light continuous draw rather than high-current bursts.
Practical interface limits
The holder presents bare contacts or short leads for soldering, so connection reliability depends on the quality of your joints. Polarity is fixed by the internal battery orientation, and the switch interrupts the positive rail only. No voltage regulation or protection circuitry is present, so the load must tolerate the full 4.5 V down to the cells' end-of-life voltage.

Questions about this item
Will this 4.5V holder stay cool and silent when left on all day?
The enclosed ABS case holds three AA cells with a simple on/off switch, so it generates no fan noise and negligible heat during continuous use.
What must I already own to get 4.5V from this 160mm holder?
You need three 1.5V AA batteries; the holder itself only provides the contacts, switch and wiring.
Can I power a legacy 4.5V device that used a proprietary battery pack with this holder?
Yes, if the device accepts 4.5V via bare wires or a compatible connector, the holder’s switch and lead length make it a direct external replacement.
